On Mars, if you hit a baseball, the height of the ball at time t would be modelled by the quadratic function h(1) = -1.85t^2 + 20t + 1,
where r is in seconds and h(1) is in metres.
a) When will the ball hit the ground?
b) How long will the ball be above 17 m?

Bugs bunny was 33 meters below ground, digging his way toward pismo beach, when he realized he wanted to be above ground. he turned and dug through the dirt diagonally for 80 meters until he was above ground

Simplify the expression 10/11(22z) + (a+5) -1

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e. g. 98.7654). x f(x) 0 1 2 3
